KNOT-TYING MECHANISM FOR GRAIN-BINDERS.

SPEGIFIGA'IION forming part of Letters Patent No. 536,698, dated April 2, 1 895. Application filed November 18,1886. sealant. 219,246. (No model.)

To all whom it may concern:

Be it known that I, MOSES A. KELLER, a citizen of the United States, residing at Batavia, in the county of Genesee and State of New York, have invented a new and useful Improvement in Knot-Tying Mechanism for Grain-Binders, of which the following is a specification.

Myinvention relates to improvements in knot-tying mechanism, in which a hook knotter and the disengaging mechanism are journaled together in a single bearing, and aknife for severing the cord also carriedaround the 'knotting hook, and it further consists of a cord supporting hook that also revolves with the disengaging mechanism, and it consists further in various other points, that will be pointed out in the specification and claims.

The object of my improvements are to simplify the knotting mechanism for grain binders, and to make them absolutely sure; in binding every bundle. I accomplish these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a right hand side elevation. Fig. 2 is a left hand side elevation. Fig. 3 is a vertical sectional view, taken through the line X XFig. 1. Fig. 4 is a rear side elevation, and Figs. 5 to 10, are detail views. Fig. 11, represents a right hand side elevation of the knotter with the binding needle in position during the knotting operation. Fig. 12, is a detail view of the knotter operating wheel, and cord clamping ring showing the former in gear with the latter at the time'the ring is rotated, which operation is also shown in Fig. 11, giving a side view of the cogs of wheel 0, and Fig. 13, is a full plan of the looping hook with the cord looped just prior to the opening of the clamping jaw, and represents the position of the hook and cord in Fig 11.

Similarletters referto similar parts throughout the specification, in which- A, is the main knotter frame in which are journaled the. main knotter operating shaft B, and the knotting hook D, and the sleeve F. Affixed tothe .upper ends of the shaft of said knotting'hook and of the sleeve are segmental pinions J, and K. A segmental bevel wheel 0, is secured upon the shaft B, which at the proper time causes the pinions J and K, to revolve. Upon the under side of the knotting hook, and affixed to a shaftf' is a clamping jaw E, and aspring M, at the upper end of said shaft f and connected to the knotter shaftor pinion K, holds the clamping jaw closed. An arm L, is also affixed to the s'haftf' at its upper end which operates in conjunction with the stop I) on the face of the bevel wheel 0, and causes the clamping jaw E, to open, at the proper time as will appear farther on.

The sleeve F,that is journaled in the frame A, is provided at its lower end next to the knotting hook, with a cord supporting hook I, and the disengaginghookG, and also with a knife H, for severing the binding cord.

The knotting hook has upon its upper side a projecting flange d that is concentric with the shaft of the hook, and the disengaging hook G, and supporting hook I, move along the inside of said flange. The point of the disengaging hook is thus enabled to get under the cord to strip it off the hook at the proper time. The knife H, revolves around on the outside of the knotting hook, and at the proper time severs the binding cord, which enables the disengaging hookG, to strip the loop off the knotting hook. Rigidly formed upon the flange d, is a horn or projection d. When the knotting hook D, is set in motion said horn will engage the cord that rests upon the hook I, and cause the cord to be lifted off said hook I, and carried around with the knotting hook D, and cause the cord to pass over the jaw E, to form the loop as seen in Fig.8. It also prevents the cord from being pushed back upon the knotting hook when passing under the point of the disengaging hook G, to enable the latter to get behind the cord to strip the same off the hook D.

Journaled upon the main shaft B, is a swinging frame N, to which is fitted the notched cord holding ring P. A grooved clamping shoe S, is pivoted to said swinging frame, and a spring R, serves to hold the shoe in contact with the notched ring. riphery of the notched ring, are cogs b, which gear-with the flange b', that is on the periphery of the bevel wheel 0, and the spiral cogs A, on said wheel cause the ring I, to move one notch to each revolution of the wheel 0, and the flange b locks the ring in its normal position, as the cogs pass out of Upon the outside pe- IOO gear. A lever O,journaled to the main frame,

f" on the frame moving in the slotf' in the lever causes the frame N, to yield up the cord at the proper time during the tying operation.

In Figs. 1, 2, 5, 6, and 7 the knotter is represented in its normal position with one end of the cord in position on thehook and holder. When the binding needle carries the cord around the bundle it places the other end of the hand right by the cord shown in the drawings. When the cord has thus been placed in position, the pinion K, is set in motion by the cogs a of the wheel 0. This sets in motion the knotting hook D, and gives it one complete revolution, no more, no less. This forms the loop of the knot, in the manner shown in Fig. 8. Simultaneously with this action of the knotting hook, the frame N, was caused to yield up the cord by the action of the cam on the back side of the wheel 0, through the lever mechanism before described. It will be seen in Fig. 8, that the clampingjaw E, is open, and the cord has dropped between the open jaws. The opening of the jaw E, was caused by the arm L, coming in collision with the stop b on the face of wheel 0. The cam T on the back side of the wheel, 0, now moves the frame N, back from the knotting hook, and thereby positively draws the cord up between the clamping jaws of the knotting hook, and at the same time the cogs a have engaged with the pinion J. This has put in motion the knife II and disengaging hook, G, but before the knife has arrived at the cord, the cam L, has passed off the stop I) and the spring M, caused thejaw E, to close on the cord. The knife now severs the cord, between the knotting hook, and the clamping mechanism of frame N, in the manner shown in Fig. 9, and the loop is disengaged from the knotting hook by the hook G, in the manner shown in Fig. 10. This completes the knot on the band around the bundle, and the bundle is free to pass out of the binding mechanism, and the cord is again placed in position on the supporting hook I, as represented in Fig. 1.

The operation of the knotter in forming and completing the knot proper, and independent of the cord holding mechanism is as follows: The normal position of the knotter proper is represented in Figs. 1, 2, 5, and 7, with the cord on hook I, and passing over the point of the looping hook D, as represented in Figs. 1 and 5. When the binding needle W begins to rise to bring the cord around the bundle and having placed it on the hook I, and into the clamping mechanism the two strands of the cord are in the position shown in Figs. 8, 9, and 11. Si-

multaneously with the starting of the needle the knotter operating wheel 0, also commences its rotation in the direction of the ar- 1 row see Fig. 11, and the moment the cord has been placed on the knotting hook as above seam stated the wheel C, has advanced far enough to bring the cogs a" up to the pinion K, and as the wheel 0, continues to rotate the cogs a set in motion the looping hook D, in the direction of the arrow. The hook D, passes around the cord and the horn d on the flange d of hook D, engages the cord and takes it off the supporting hook I, and throws it over the heel of the hook D, as represented in Figs. 11 and 13. When the hook D, has arrived where it stands in Figs. 11 and 13, the arm L that con trols the clamping jaw E, is arrested by the cam or stop I)", that is on the face of the wheel 0, and as the hook D, moves on, it opens away from the jawE and the cord that is between the knotter and holding mechanism slips into the open space on the knotting hook D. By this time the cam b" has passed the arm L, and the spring M closed the jaw E on the cord and clamped it against the hook d just a little before the hook D'completes its revolution and in the meantime the pinion J, that is on the sleeve F, has also been put in motion and the disengaging hooks G, and knife 11 and hook I, that are in the sleeve F, have advanced sufficiently by the time the cord was clamped by the jaw E, so that the knife I-I, immediately cuts the cord as represented in Fig. 9 and the hook G strips the loop off the beak or book D, and the bound bundle is free to pass out. The hook I, will come around to take up its normal position to receive the cord before the needle has receeded too far. The cams sand 0' on the face of the wheel 0, look the knotter pinions in their normal position when out of gear with the segments of'said wheel. The wheel 0, makes but one revolution to each tying operation.
